v0.6.3

• Resolved bug in roach .bck file excluding nop instruction. closes issue #6
• Refactored Schedule class extracting dependencies. Work in progress for web release.
• Added explicit ftrack parameter in configuration file. closes issue #8
• Added offset interleave parameter in raster map scans. closes issue #9
• Angles representation is now rounded to the 4th decimal point. closes issue #7
• Fixes algorithm for Raster Map scans using multifeed receiver. closes issue #10
• Optimization of subscan management removing redundancy during repetitions. Also optimizes onoff and nodding scans. closes issue #11

Note on ftrack: in order to use ftrack procedures the user now must specify

restFrequency = something_different_from_zero
ftrack = True

in the configuration file. Note that this will activate ftrack procedures even
when the target velocity is null. On the contrary, setting a restFrequency
value and a target velocity will not automatically trigger the ftrack
procedure if not explicitly specified by the ftrack parameter in the
configuration file.

Note on raster maps: Raster maps now include a new parameter called
offset_interleave. If offset_interleave is differrent from zero this
will tell basie to add one subscan outside the map after offset_interleave
subscans inside the map.By default the offset position is taken 5 beamsizes
outside the map perimeter for single feed receivers, while it is taken 5 receiver-extents
outside the map for multifeed receivers.
