Fix test function groupbars. Random number generator is reinitialized to always return same random values.
Remove dependence of function "rng", since it is not present in octave
Rename option "group" to "grouped", since "group" is not a valid option name.

Fix conversion of degree symbol "°"
* add handling of ">>", meaning much greater
* adapt ACID test 74 to test this
This however needs "parseStringsAsMath" to be "true", otherwise this fails, as described in issue #402.
Modify ACID test 74 decayingarmonic to include "much greater", "much smaller", "greater" and "smaller" ("<<", ">>", ">", "<") in the title to test handling of those characters.
Properly handle symbols "<", ">" (smaller, greater) if "parseStringsAsMath" is deactivated.
Handle possible tex error `double superscript` or `Missing {` for the strings `x^°` and `x_°` by proper escaping. Thanks go to @egeerardyn for pointing out the problematic case.

Add `formatDim` with limited precision. Fixes #396

The precision is set to 6 decimal to format TeX dimensions.
As discussed in #396 by @okomarov, 5 decimals is ample resolution
for any practical use.

Trailing zeros and dots are removed for prettiness.

Moreover, when a TeX length (e.g. `\figurewidth`) is used as unit,
1.0 is converted into just the unit.
