Inner Class Summary
`private class` | `VelocimacroFactory.Twonk` small continer class to hold the duple of a template and modification time.

Field Summary
`private boolean` | `addNewAllowed` controls if new VMs can be added.
`private boolean` | `autoReloadLibrary` determines if the libraries are auto-loaded when they change
`private boolean` | `blather` controls log output
`private java.util.Map` | `libModMap` map of the library Template objects used for reload determination
`private java.util.Vector` | `macroLibVec` vector of the library names
`private boolean` | `replaceAllowed` determines if replacement of global VMs are allowed controlled by VM_PERM_ALLOW_INLINE_REPLACE_GLOBAL
`private RuntimeServices` | `rsvc` runtime services for this instance
`private boolean` | `templateLocal` sets if template-local namespace in used
`private VelocimacroManager` | `vmManager` VMManager : deal with namespace management and actually keeps all the VM definitions

Constructor Summary
`VelocimacroFactory(RuntimeServices rs)` CTOR : requires a runtime services from now on

Method Summary
`boolean` | `addVelocimacro(java.lang.String name, java.lang.String macroBody, java.lang.String[] argArray, java.lang.String sourceTemplate)` adds a macro to the factory.
`private boolean` | `canAddVelocimacro(java.lang.String name, java.lang.String sourceTemplate)` determines if a given macro/namespace (name, source) combo is allowed to be added
`boolean` | `dumpVMNamespace(java.lang.String namespace)` tells the vmManager to dump the specified namespace
`private boolean` | `getAutoload()` get the switch for automatic reloading of global library-based VMs
`private boolean` | `getBlather()` get output message mode
`private boolean` | `getTemplateLocalInline()`
`Directive` | `getVelocimacro(java.lang.String vmName, java.lang.String sourceTemplate)` actual factory : creates a Directive that will behave correctly wrt getting the framework to dig out the correct # of args
`void` | `initVelocimacro()` initialize the factory - setup all permissions load all global libraries.
`boolean` | `isVelocimacro(java.lang.String vm, java.lang.String sourceTemplate)` Tells the world if a given directive string is a Velocimacro
`private void` | `logVMMessageInfo(java.lang.String s)` localization of the logging logic
`private void` | `logVMMessageWarn(java.lang.String s)` localization of the logging logic
`private boolean` | `setAddMacroPermission(boolean arg)` sets the permission to add new macros
`private void` | `setAutoload(boolean b)` set the switch for automatic reloading of global library-based VMs
`private void` | `setBlather(boolean b)` set output message mode
`private boolean` | `setReplacementPermission(boolean arg)` sets the permission for allowing addMacro() calls to replace existing VM's
`private void` | `setTemplateLocalInline(boolean b)` sets permission to have VMs local in scope to their declaring template note that this is really taken care of in the VMManager class, but we need it here for gating purposes in addVM eventually, I will slide this all into the manager, maybe.

### replaceAllowed

    private boolean replaceAllowed

  determines if replacement of global VMs are allowed controlled by VM_PERM_ALLOW_INLINE_REPLACE_GLOBAL

### addNewAllowed

    private boolean addNewAllowed

  controls if new VMs can be added. Set by VM_PERM_ALLOW_INLINE Note the assumption that only through inline defs can this happen. additions through autoloaded VMs is allowed
