wasm for JsMacros,
to declare jsmacros stuff, you need to know the rules for how we deal with java objects. if it has a direct wasm equivelent (like an integer), it uses that, if it has an indirect equivelent (like short/char/byte/boolean) it's an i32. if it's a String: as a parameter it's a c-string pointer, as a return value, it will return a jPtr to a java string. otherwise it's a jPtr.
wasmtime doesn't like method overloads, so if there are multiple of the same method in a class, it will get the number of args appended to the method name, for example there are 2 post methods in Request,
hence they will be post2 and post3,
if this still isn't enough to distinguish them, they will simply be numbered in the natural ordering (top to bottom),
so for example there are 3 total getBlock methods in World.
these would be getBlock3, getBlock1_1 and getBlock1_2
a jPtr is an i32 pointer to a java object, to actually use it, see the
Java module, which provides manipulation and visibility for java objects.
converts a java string to a c-string, you must provide a ptr for an array to offset
the array length is required to be exact for a c-string, meaning you must include room for the null terminator.
converts a c-string to a java string
prints the canonical class name of the java object at the ptr to a new jPtr that contains a java string.
invokes java method, requires signature of the method, argPtrs is array of pointers/jPtrs.
