parseScanimageTiff bug fix
fixed slicing error
Added support for SI3 in parseScanImageTiff

parse function now checks for signature of SI version in metadata, and
uses this to appropriately determine movie information
calcSeedCovBin non-square movie bug fixed

Function incorrectly assumed movie was square in size when it generated
x,y pixel position matrices, as well as for x,y seed positions
readRaw compatability with parseScanImage change

No longer removes SI4 field, since this will later throw error. Also now
throw an error from parse function if it fails to get metadata
minor SC2Pinit change

tries to find 'nameplace' variable inside try loop, to prevent error if
automatic naming fails
nBasis parameter setting in lucas Kanade

nBasis now passed from parameter setting block of code as argument to
single frame function, and not required in single frame function
Drastically reduced nBasis

Appeared to get much more consistent results with fewer basis, but this
is somewhat experimental...
New auxiliary initialization

for creating initializations with default lucasKanade motion correction
minor display/documentation improvements
multiChannel reference bug in lucasKanade

Code line calculating meanRef was outside of the channel loop instead of
inside
meanRef multichannel/slice bug fix

input handling fixes
CAR added my initialization file
motionCorrect modified to use signed integers

Requires updated tiffWrite function from helperFunctions, which
implemented support for signed integers in tiffWrite
changed second half of fxn to work with scanimage 3
