Get files

Retrieves cell array of file names from current directory

[Sacs] = getFiles(varargin);
This function returns a cell of file names from the current directory, given any number of inputs of regular expressions. It is analogous to the LINUX 'ls' command, but the output is given to the user as a cell, when using getFiles.m

USAGE
[Sacs] = getFiles('REGEXP1','REGEXP2',...,'REGEXPN');

INPUT
REGEXP1: A character regular expression, such as 'get' or 'mat'.

OUTPUT
Sacs: A cell array containing the file names that match the
requested character matches.

EXAMPLES
Suppose you have a directory where JPEG images are stored under names that include 'November' somewhere in the title. This returns those file names:

[Sacs] = getFiles('November','.jpg');

Suppose you have directory containing data of the form:
STATION.CHAN.YEAR.DAY.HR.SAC
The following command returns all .SAC files for station 'JAN', channel 'EPZ', Julian day 340, and year 2009:

[Sacs] = getFiles('SAC','JAN',340,2009);
