Implemented program to plot ground truth in 2d
Added a function for setting GT of images in folder

GTFROMDIR is a function that uses ObtainGT and plotGT to read images
from a directory and saves a workspace with variables containing the
ground  truth for the images.
Function adds '/' to dir and only plots if GT obt.

Function needs ’/’ at the end of the directory

Only plots GT in image if it gets obtained.
Added feedback when obtaining gts
Added plot GT from dir

Plots the GTs from images in specified dir, with the GT saved as .mat
in the folder above
Changed function to output a struct array instead.
Changed gtRaw2gtData so that the pepperData struct has the unit vector inclination instead of thetax and thetaz.
plotting of inclination added.
Fixed dates in changed methods.
Spheroid now takes a unit vector.
plotPeppers plots ellipseoid although the peropendicular major ellipse is missing.
plotPepper now has the same functionality as previously.
Deprecated fitFrom2Deg.
Merge pull request #2 from niclasborlin/gt2d

Gt2d
Moved gt2d to src where it belongs.
Merge pull request #3 from niclasborlin/representInclinationAsUnitVector

I tested it against the image in the office and it seems to coincide.
alignPeppers now takes arrays instead of awkward structs.
Teh demo code.
Added so that the demo script plots gt and meashure separately (also).
Merge branch 'demoLinusMartinJakob' into pointCloud2Ellipsoid
