Implemented basic variant of Monte-carlo simulation for all Dynamic Models in FireVoxel.

User starts with obtaining the required ROI and saving it to the file.

User create a 4D-volume from the specified TAC setting the level of noise (10% in this example). Then runs the chosen model over the 4D volume, where each voxel corresponds to the original TAC+ random Noise.

Resulting is the map(s) of the selected parameters (K1 in this example).

Next user is able to do some basic statistics on the specified parameter, K1 in this case.

Corrected and updated the "Open TAC as 4D volume" function.  This allows user to specify the *.TXT file containing the TAC.  User specifies dimensions of the resulting volume where which voxel is constructed given the specified TAC + random Noise (Noise level is specified by the User).

This functionality allows to perform Monte-Carlo modelling of the Dynamic Models.

Single Timepoint of the resulting volume where vox(x,y,z) = TAC[t]+RandomNoise(x,y,z)
