csv2cellfast - import CSV files on machines without Excel

Parses a Windows CSV file into an NxM cell array if strings.

A rewritten CSV importer inspired by Arthur Hebert's function.

Vector operations are used instead of loops, which leads to 2x to 10x speed improvements.

Files with a large number of quoted cells (cells that include comma and quote characters) will be slower to be import.

Tested with reasonably large files, with success.
