TODO:
0) Figure out a error handling scheme that does not rely on
a global errno. This is not useful in multi-thread environments.
It might be ok to go with an 'all errors are fatal' model
(except in the var-args functions).
Consider the use of a context object for use with functions
that can have runtime errors or need to allocate memory.
1) Implement the canConvert and willTruncate functions.
2) Make a set of cmDataAllocXXXPtr() functions which take
a flag indicating whether or not to dynamically allocate
the array space. This will allow dynamic allocattion to
occur at runtime. Make var args functions for list and
record objects which also take this flag.
Where ever a function may be implemented using
static/dynamic allocation this flag should be present.
(e.g. string allocation for pair labels)
This choice is common enough that it may be worth
suffixing function names with a capital letter to
be clear what the functions memory policy is.
3) Come up with a var-args format which allows a
hierchy of records to be defined in one line.
4) Implement the serialization functions.
5) Implement an ascii string/parse format for writing/reading.
6) Implement fast lookup of record fields.
7) Allow for user defined types. For example a 'matrix'
data type. This might be as simple as adding an extra 'user_tid'
field to cmData_t.
8) Implement type specific cmDataGetRecordValueXXX() functions.
9) Implement cmDataIsEqual(), cmDataIsLtE(), ...
