validateInput

validateInput started when creating saveppt2. There was a need to take a large number of inputs, in any order, and make them usable to the script. Checking if an input argument has been passed can be done with isfield or if the 'force' option is enabled if the field is false.

Examples:
varargin={'p','s',10,'name','john doe'};
validParameters={{'size','s'},{'print','p'},'name'};
parameters=validateInput(varargin,validParameters)
parameters =
print: 1
size: 10
name: 'john doe'

varargin={'p'}
validParameters={{'size','s'},{'print','p'},'name'}
parameters=validateInput(varargin,validParameters,true)

parameters =
print: 1
size: 0
name: 0
