* When kjs parses some code, it generates a source code fragment (or just "source").
|
|
* This is referenced by its source id in future calls to functions such as atLine()

|
* and callEvent(). We keep a record of all source fragments parsed in order to display
|
|
* then to the user.
|
|
*
|
|
* For .js files, the source fragment will be the entire file. For js code included
|
|
* in html files, however, there may be multiple source fragments within the one file
|
|
* (e.g. multiple SCRIPT tags or onclick="..." attributes)
|
|
*
|
|
* In the case where a single file has multiple source fragments, the source objects
|
|
* for these fragments will all point to the same SourceFile for their code.
