* parseExpression(sExp, fPrint)
*
* A quick-and-dirty expression parser. It takes an expression like:
*
* EDX+EDX*4+12345678
*
* and builds a value stack in aVals and a "binop" (binary operator) stack in aOps:
*
* aVals aOps
* ----- ----
* EDX +
* EDX *
* 4 +
* ...
*
* We pop 1 "binop" from aOps and 2 values from aVals whenever a "binop" of lower priority than its
* predecessor is encountered, evaluate, and push the result back onto aVals.
*
* Unary operators like '~' and ternary operators like '?:' are not supported; neither are parentheses.
*
* However, parseReference() now makes it possible to write parenthetical-style sub-expressions by using
* {...} (braces), as well as address references by using [...] (brackets).
*
* Why am I using braces instead of parentheses for sub-expressions? Because parseReference() serves
* multiple purposes, the other being reference replacement in message strings passing through replaceRegs(),
* and I didn't want parentheses taking on a new meaning in message strings.

* a string beginning with a letter or underscore, followed by zero or more additional letters,
* digits, or underscores) and the property value is the variable's numeric value. See doVar()
* and setVariable() for details.
*
* Note that parseValue(), through its reliance on str.parseInt(), assumes a default base of 16
* if no base is explicitly indicated (eg, a trailing decimal period), and if you define variable
* names containing exclusively hex alpha characters (a-f), those variables will take precedence
* over the corresponding hex values. In other words, if you define variables "a" and "b", you
* will no longer be able to simply type "a" or "b" to specify the decimal values 10 or 11.

* parseExpression(sExp, fPrint)

* EDX+EDX*4+12345678
*
* and builds a value stack in aVals and a "binop" (binary operator) stack in aOps:
*
* aVals aOps
* ----- ----
* EDX +
* EDX *
* 4 +
* ...
*
* We pop 1 "binop" from aOps and 2 values from aVals whenever a "binop" of lower priority than its
* predecessor is encountered, evaluate, and push the result back onto aVals.
*
* Unary operators like '~' and ternary operators like '?:' are not supported; neither are parentheses.
*
* However, parseReference() now makes it possible to write parenthetical-style sub-expressions by using
* {...} (braces), as well as address references by using [...] (brackets).
*
* Why am I using braces instead of parentheses for sub-expressions? Because parseReference() serves
* multiple purposes, the other being reference replacement in message strings passing through replaceRegs(),
* and I didn't want parentheses taking on a new meaning in message strings.
