+LzmaRamEncode: BCJ + LZMA RAM->RAM compressing.
+It uses .lzma format, but it writes one additional byte to .lzma file:
+  0: - no filter
+  1: - x86(BCJ) filter.
+
+To provide best compression ratio dictionarySize mustbe >= inSize
+
+LzmaRamEncode allocates Data with MyAlloc/BigAlloc functions.
+RAM Requirements:
+  RamSize = dictionarySize * 9.5 + 6MB + FilterBlockSize 
+    FilterBlockSize = 0, if useFilter == false
+    FilterBlockSize = inSize, if useFilter == true
+
+  Return code:
+    0 - OK
+    1 - Unspecified Error
+    2 - Memory allocating error
+    3 - Output buffer OVERFLOW
+
+If you use SZ_FILTER_AUTO mode, then encoder will use 2 or 3 passes:
+  2 passes when FILTER_NO provides better compression.
+  3 passes when FILTER_YES provides better compression.
