Added max_mem and removed strategy and options.

Functions have not yet been tested in Pycroscopy.
Functions need to be updated to follow Pycroscopy standards.

Now reads the first image in the list whether or no a crop is set to get the needed parameters for dataset creation.

Added win_fft variable to top of script that specifies which fft option to use when creating the windows.

Fixed reshapes to ensure that the position and spectroscopic indices are 2d when not passed as arguments.

Use buildReducedSpec to create the ancillary metric datasets
New class attributes and initial values of some existing ones
Impemented doGuess method
New methods - _get_projection_data, _project_loops, and _getDataChunk
Changed how the DC Offset and FORC were tracked
Changed some local variables to Class attributes
Only track overall position index, not the indices for each dimension
Fix for reshaping metrics when the only spectroscopic dimension is FORC
Make sure that loop fits are 2d
Minor PEP8 format changes

Added default solutions for x and y intercepts when geometric solution fails.
Small formatting changes

clean up of plot_utils. PEP8 cleaning. Cleared confusion regarding the names of the clustering plotting functions

clean up of plot_utils. Removed redundant plotSpectrogram and plotBELoops functions and generalized others.

cleaned up visualizeSHOResults substantially and this method only uses plot_map_stack and plot_loops.

Simplified plotVSsnaps. This method will be removed and so will plotSpectrograms
minor PEP8 cleaining

plot_map_stack now has fewer rows and more columns wherever possible to suit common screen resolutions.
Using plot_map_stack instead of plotSHOMaps now. Latter function was redundant and therefore removed.
minor PEP8 cleaining

Renamed the existing 'abs' option to 'data+abs'
New windowing option 'abs' only has the magnitude of the 2d FFT

Cnms dev

Updated the script to take into account the new changes to the window datatypes and to do KMeans.

Added support to save the absolute magnitude of the 2d FFT of the windows or the full complex 2d FFT
Added custom datatypes for three supported windowing FFT options

Updated the doSVD function to use the transformToTargetType and transformToReal functions

Fixed a bug with not initializing the spectroscopic indices of the Mean Response 

Updated functions to allow for compound dtypes with only one field.
