Implement Preprocessor #include with StringBuilder

Demonstrates how to implement #include with a Chilkat StringBuilder. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    //  First build a string that has a preprocessor include
    CkStringBuilder sbSrc = new CkStringBuilder();
    sbSrc.Append("1\r\n2\r\n3\r\n");
    sbSrc.Append("#include <qa_data/txt/helloWorld.txt>\r\n");

    //  	1
    //  	2
    //  	3
    //  	#include <qa_data/txt/helloWorld.txt>

    //  sbSrce now contains:
    //  	1
    //  	2
