The aim of this version was to improve the handling of events superimposition. This option now has its own tab and set of controls in the DetectedEvents window, and a set of new features:
* the user can superimpose tagged events and their mean + SD (including the synchronous signal in the other channel), using a set of pre-defined colors or random colors.
* Normalization (to an arbitrory segment of the trace chosen by the user) is optional; a cursor can highlight the portion of the trace that serves as a reference for normalization.

Bug fix #1: the files open through the Load button were kept open, preventing to save the experiment. Fixed adding "Close RefNum".
Bug fix #2: bug in the new function which concatenates and load multiple waves. With a long list of waves, the string containing the list was too long. Changed the concatenation process to prevent this (the new concatenation is incremental).

* This version adds a significant improvement: users can now load waves from IGOR's data folders. Whether SpAcAn will load waves from the disk (as before) or from a datafolder is determined using checkboxes. Local waves are loaded through a dialog. Multiple waves can be concatenated and loaded as a single wave.
* Another handy improvement is the possibility of detecting positive deflexions (in addition to negative deflexions). No more need to flip the waves before detection for positive deflexions (e.g. EPSPs or spikes). The flip function is still there.

SpAcAn version 1.02-2
Adds a measure of the time of the "foot" of individual events (intersection of the baseline with the 20%-80% rise time line) (function DETECT).
Adds a button in the window DetectedEvents to superimpose tagged events. Events can be aligned on their "foot" time, half-rise time or peak time.
Fixes a bug in function LoadABF which was causing the function to abort.
Adds better graphs for Freq/Amp plots.
Fixes a bug related to saving the analysis parameters in the wave "params".
Some code cleanup.
