// - Do this across a large area, at least 2000x2000 blocks for good numbers
// - Open logs\gregtech.log
// - Using notepad++, do a Search | Find - enter "Added" for the search term
// - Select Find All In Current Document
// - In the Search window, right-click and Select All
// - Copy and paste to a new file
// - Delete extraneous stuff at top, and blank line at bottom. Line count is
// # of total oreveins
// - For simple spot checks, use Find All in Current Document for specific
// oremixes, ie ore.mix.diamond, to check how many appear in the list.
// - For more complex work, import file into Excel, and sort based on oremix
// column. Drag select the oremix names, in the bottom right will be how many
// entries to add in a seperate tab to calculate %ages.
