Coding Standards for CIVL models

1. place one blank line between elements in a file (an element is a variable, method, or type definition, etc)
2. all local variables declared in a block (i.e., a compound statement in curly braces) should appear at the top of the block, followed by a blank line, followed by the statements in that block; this greatly enhances readability
3. break up a function into smaller pieces if it gets too long
4. use two spaces for alignment
