+	Main idea of CBufferString is to provide the base class for the CBufferStringGrowable wich implements stack allocation
+	with the ability to convert to the heap allocation if allowed.
+
+	Example usage of CBufferStringGrowable class:
+ 
+	* Basic buffer allocation:
+	```
+		CBufferStringGrowable<256> buff;
+		buff.Insert(0, "Hello World!");
+		printf("Result: %s\n", buff.Get());
+	```
+	additionaly the heap allocation of the buffer could be disabled, by providing ``AllowHeapAllocation`` template argument,
+	by disabling heap allocation, if the buffer capacity is not enough to perform the operation, the app would exit with an Assert;
+
+	* Additional usage:
+	CBufferString::IsStackAllocated() - could be used to check if the buffer is stack allocated;
+	CBufferString::IsHeapAllocated() - could be used to check if the buffer is heap allocated;
+	CBufferString::Get() - would return a pointer to the data, or an empty string if it's not allocated.
+
+	* Additionaly current length of the buffer could be read via CBufferString::GetTotalNumber()
+	and currently allocated amount of bytes could be read via CBufferString::GetAllocatedNumber()
+
+	* Most, if not all the functions would ensure the buffer capacity and enlarge it when needed,
+	in case of stack allocated buffers, it would switch to heap allocation instead.
