This adds a String overload for AssertSoft.
Previously only integer weights could have been used,
limiting the user. With Strings the user can now use
e.g. Java's BigInteger class converted to a String instead.
* Generify, needs some testing and review
* Remove unnecessary change
* Whoops, ? capture that type
* Misread the docs, whoops
* More permissible arithmetic operations
* Implement believed Optimize generics
* Missed a few generics
* More permissible expr for arrays in parameters
* More permissible expr for bitvecs in parameters
* More permissible expr for bools in parameters
* More permissible expr for fps in parameters
* More permissible expr for fprms in parameters
* More permissible expr for ints in parameters
* More permissible expr for reals in parameters
* Undo breaking name conflict due to type erasure; see notes
* Whoops, fix typing of ReExpr
* Sort corrections for Re, Seq
* More permissible expr for regular expressions in parameters
* Fix name conflict between sequences and regular expressions; see notes
* Minor typo, big implications!
* Make Constructor consistent, associate captured types with other unknown capture types for datatype consistency
* More expressive; outputs of multiple datatype definitions are only known to be sort, not capture, and Constructor.of should make a capture
* Be less dumb and just type it a little differently
* Update examples, make sure to type Expr and FuncDecl sort returns
* General fixups
* Downgrade java version, make it only for the generic support, remove var and Expr[]::new construction
* Turns out Java 8 hadn't figured out how to do stream generics yet. Didn't even show up in my IDE, weird
