* About class:
* SpiderEngine v.1.1.0 class for spidering any html page
*   -fetchData() - for reading the content of a html page
*   -processData() - for doing whatever you want to the results
*     -url - url to read from eg.<range[0]>.html
*     -range - array for range of action on url eg. array(0=>array("start"=>1,"end"=>10,"step"=>1)) - that means: for(i=1;i<=10;i+=1)
*     -pattern - the html text containing the pattern_definition and text

*     -start - from where the spider reads the content of the page
*     -end - array of "to_process" and "not_to_process" content, if a text from array "to_process" was found in content page then the data is spidered and is called processData(), if a text from array "not_to_process" was found in content page then just show a message
*     -pattern definition example: {p[abc]}, {p[1]},{p[#]},{p[no.1]} etc.
*   -pattern can be found in the same page multiple times

Because I saw MineTheWeb (which appears to be the most used commercial spider) and I didn't like it at all, I started working on a general spider for html that uses the logic of MineTheWeb, but with improvements ! And FREE for use!
