A new version of the midas sequencer has been developed and now available in the 
develop/seq_eval branch. Many thanks to Lewis Van Winkle and his TinyExpr library 
(https://codeplea.com/tinyexpr), which has now been integrated into the sequencer 
and allow arbitrary Math expressions. Here is a complete list of new features:


* Math is now possible in all expressions, such as "x = $i*3 + sin($y*pi)^2", or 
in "ODBSET /Path/value[$i*2+1], 10"


* "SET <var>,<value>" can be written as "<var>=<value>", but the old syntax is 
still possible.


* There are new functions ODBCREATE and ODBDLETE to create and delete ODB keys, 
including arrays


* Variable arrays are now possible, like "a[5] = 0" and "MESSAGE $a[5]"


If the branch works for us in the next days and I don't get complaints from 
others, I will merge the branch into develop next week.
