Porting easyMesh to other platforms

Could you add in Readme.md a little summary about the userfulness of each of these libraries?

Thanks

crashes after N items have been added?

The code below on an Uno crashes after ~60 iterations of adding an instance of foo to the list.

This is a minimized version of the code I'm developing right now. My initial feeling is that I've messed up a pointer somewhere (it's been a while since I worked in raw C++, forgive me) so please point it out if I've done something moronic somewhere, I can't spot it.

Otherwise, varying the size of the s variable make it crash quicker the longer the string is, but the total size of an instance of foo with s=="s" should be really small, so I can't see how I'd exceed the available memory at 60 instances.

Here's the sketch output size info:
Sketch uses 4,068 bytes (12%) of program storage space. Maximum is 32,256 bytes.

Global variables use 302 bytes (14%) of dynamic memory, leaving 1,746 bytes for local variables. Maximum is 2,048 bytes.

Thanks!

include <Arduino.h>

include "SimpleList.h"

class foo
{
public:
String* s;
foo(void)
{
//the size of this string can be reduced, the longer it is, the quicker the crash- it's not just an issue because it's a long string
//this one takes ~13 iterations to die
//s=new String("sdfsdfhjfhgvbjkhlyuithgdfcnbvmj,hlkiyuitythdgcvnbm,jhlyuityurthgcnbvm,jhliyuityrhgdcnbvm,jhlyuityurthgcnbvmj,hluyityurthdgcvnbmj,hkuytiyfghvhjkuyitufg");
//this string makes it take 60 iterations
s=new String("s");
}
};
void setup()
{
Serial.begin(19200);
SimpleList<foo*>* list = new SimpleList<foo*>();
//list->reserve(100); //reserving up front doesn't seem to matter
for(int i=0; i<60; i++)
{
foo* f = new foo();
list->push_back(f);
}
}
void loop() {}
