+Built-in Data Types:
+--------------------
+bool
+int
+uint
+float
+double
+symbol
+string
+
+boolM
+intM
+uintM
+floatM
+doubleM
+symbolM
+stringM
+
+function
+
+array   : mixed type arrays 
+struct  : user definable structures
+
+
+Support Functions:
+copy()
+toString()
+fromString()
+Math Op's.
+String Op's.
+Custom ops of the form: function( const struct* inputs, struct* outputs ).  
+
+
+
+Functions:
+----------
+List of named inputs and outputs, implemented according to the
+above data types, along with known functions:
+
+Constructor()  : Allocate object based on resource struct.
+Destructor()   : Release object.
+Setup()        : Determine runtime configuration based on input types.
+Exec()         : Audio rate execution.
+SetInput()     : Control rate updates.
+GetValue()     : Query state values.
+StoreState()   : Store the current state of the object as a preset.
+RestoreState() : Recall a previously stored preset.
+
+
+User Interface:
+---------------
+The user interface is formed by instantiating user interface
+elements for function inputs.  In this way most user interface
+elements do not have to be explicitely connected because they
+are inherently connected.  This does not preclude either
+connecting the same control to other functions or the use
+of UI-only functions.

+Generic System Changes:
+-----------------------
+1) Error handling:
+  - Use a predefined set of generic error codes with the possiblity of
+  adding custom codes.
+
+  - Use a generic error handler macro which jumps to 'errLabel' on fail.
+    cmErrTry( err, rc, function_returning_error_code() )
+    cmErrTryMsg( err, rc, function_returning_error_code(), "Error msg  %i ", value );
+
+
+  - Global functions, (i.e, those functions which do not have a manager) should
+    take optional error object points.  These functions include memory mgmt,
+    file mgmt, text mgmt, ...
+
+2) Develop a transparent, multi-dimensional, matrix class.
+
+3) cmCtx_t extensions.
+  - The cmCtx_t context should be considered a singleton global object, whose
+  life extends for the entire program.  This will eliminate needing to duplicate
+  the context.
+
+  - Possibly add a JSON tree to pass global program cfg. information.
+
+4) Simplify the low level processing object design.
+  - Eliminate the alternative cmCtx type and use the cmCtx_t class.
+  - Eliminate the distinction between allocation and initialization.
+
+5) Make use of thread local memory for allocating scratch memory
+   which does not need to be deleted.
+
+6) Add a cmMemPrintf() function to create dynamcially allocated formatted strings.
+
+7) Figure out the text encoding thing.
+
+8) Eliminate the cmXXXIsValid() function - this can be provided
+   by a generic function (or macro).
+
+9) Make the documentation work from the start.
