Merge pull request #100 from robertgoss/CrossComponentInheritance_msvc_warning

## Issues - #99 

## Symptom

When compiling the c++ act bindings for a cross component interface project the visual studio compiler outputs warningsof the form:

```
typedef struct {
  PAbstractCAMBase_GetLastErrorPtr m_Base_GetLastError;
  PAbstractCAMBase_ReleaseInstancePtr m_Base_ReleaseInstance;
  PAbstractCAMBase_AcquireInstancePtr m_Base_AcquireInstance;
  PAbstractCAMBase_GetVersionPtr m_Base_GetVersion;
  PAbstractCAMBase_GetSymbolLookupMethodPtr m_Base_GetSymbolLookupMethod;
} sAbstractCAMFunctionTableBase;
typedef struct : sAbstractCAMFunctionTableBase {
  PAbstractCAMLinking_CreateLinkerPtr m_Linking_CreateLinker;
  PAbstractCAMLinking_QueryStrategyPtr m_Linking_QueryStrategy;
} sAbstractCAMFunctionTableLinking;
```

## Problem

This appars to be the issue in https://developercommunity.visualstudio.com/content/problem/1034754/warning-c5208-a-c20-feature-occurs-when-compiling-1.html

In particular we define anonymous structs with member that are then typedefed

## Solution

We give a name to the function table structs based on the typedef name with "Struct" appended to make it unique.

## Verification

Recompiled bindings after the change with no warning. Tests to call the interface still pass.
