Multi-Format CSV Reader

"mfcsvread" reads a CSV file containing both text & numeric data. MATLAB's CSVREAD function will work with all numeric, or all text data, but not both. It's common to have a file with a single line of comma separated text headers followed by many rows of numeric data. xlsread is limited in the number of rows & colums (actually, Excel is the limitation) it can read.
The CSV file should look like:
comma, separated, text, ...
1,2,3,4,5,...
6,7,8,9,10,...
etc...

The output is a structure with the column headers as fields in a structure, each with a vector of data.
